If you've got a local source for strapping and buckles, make one yourself. I've found that it's the best way to get exactly what I want. If the belting is too soft it tends to fold up when tightened. It's hard to find a commercial, nylon webbing belt, that has all of your desired features. It's easier to find a good backpack.

Fortunately there are good sources in Berkeley, where I can get to them.

I made a belt from a leftover toggle thingie and a thin piece of elastic cordage. I have to slip on my pants with the belt fastened, but I left a lot of extra cordage to allow for that. Not as light as spectra cord with a fancy knot, but being able to whip your pants off in a flash can be useful if you really have to go.

Lately I've been harvesting webbing and fasteners from stuff at the thrift store.

Add a mini biner. Let the toggle catch in the narrow end and attach the biner to a loop on the other end of the cord. Now you can use the toggle to tighten the belt and in a flash you can undo the belt by unclipping the biner or sliding the toggle away from the narrow part of the biner. You are 95% there :)
